I'll call stalemate. Something I don't think people are recognizing is they only get common knowledge of each other in addition to their personal knowledge. If this is normal Batman, he doesn't know who Terry Mcguiness is. He only gets common knowledge from that person's world, i.e. Gotham of the future. This is supposedly some Batman who reappeared after years of there being no Batman. Wayne can only theorize that he would have some involvement with this future Batman.
Yet, Terry knows Batman is Bruce Wayne. This gives him a very short-lived advantage at the outset of the fight. Terry knows how Bruce thinks and fights. Bruce taught him. And that was an older and more experienced Bruce that taught Terry. By using that against him, combined with his suit's advantages in strength, agility, flight, stealth and advanced weapons, he would definitely make it tough for Batman. Imagine if Nightwing or Robin were in a suit like this and Bruce didn't know it was them inside. Nightwing or Robin would use Batman's teachings against him and probably win.
I still think Bruce could even it out though, since I consider him to be a superior H2H fighter and tactician and Terry's suit is not beyond anything Batman hasn't faced in his career. And eventually, he should be able to deduce that this future Batman knows who Bruce is and that his older self must have trained this Batman from the future. So he'd switch tactics. I've always imagined that Bruce taught Terry everything Terry knows, but he didn't teach Terry everything that Bruce knows.
Stalemate 5/10.
